Slag (welding) Wikipedia

Welding slag is a form of slag, or vitreous material produced as a byproduct of some arc welding processes, most specifically shielded metal arc welding (also known as stick welding), submerged arc welding, and fluxcored arc welding.Slag is formed when flux, the solid shielding material used in the welding process, melts in or on top of the weld zone.
